"They couldn't get either of the rear tyres off. It was a 31 second stop. Terrible news for Max Verstappen."
Daniil Kvyat pits, takes on softs, and resumes in ninth place. A clean stop. Not so much luck for Max Verstappen as Toro Rosso struggle to get his tyres off and he loses a lot of time.
Lotus driver Pastor Maldonado retired early on and has never finished a Monaco Grand Prix or any race this season: "Difficult moment. I think as a team we need to be strong and try to solve all of the problems we have had. We have had similar problems in the past and maybe brakes are where we need to focus in future."
Poor old Pastor, it is not always his fault.
Brandon: I think Hamilton will go on to win with Vettel second and Rosberg third, also McLaren scoring there first points of the season.
Dennis Lietnev: The pit stop strategies for both Hamilton and Rosberg may eventually decide this race.
Phil Slocombe: Lewis just needs to stay on the black stuff and off the barriers and he should win it to extend his points lead in the WDC.
Lewis Hamilton runs into traffic as he approaches back markers Marcus Ericsson and Carlos Sainz. He gets past with little trouble, despite reporting that he believes he lost time, and the gap between himself and Nico Rosberg is now 7.3s with 28 laps gone.

"Lewis Hamilton has been on the radio again and his engineer said: 'We are approaching the limit on brakes.'"
Lewis Hamilton's found something as he breaks 1:20 on lap 24 to clock the fastest lap and he is now 4.6 seconds ahead of Nico Rosberg, who is having to stay mindful of Sebastian Vettel 1.5s behind him.

"We always talk about the track being a living thing, you can't just collect data on Friday, you have to be on your toes reacting. Some of it is in shade, there is old tarmac and new, fresh tarmac re-laid for this year. It takes different wear patterns on the tarmac."
No-one inside the top 10 has made a trip to the pits with 21 laps gone. There's not much between the top three at all, Lewis Hamilton, Nico Rosberg and Sebastian Vettel all lapping within 0.15s of each other.
Romain Grosjean has pitted from 12th with Felipe Nasr, in 11th, swiftly following suit and both retain their position in the race when they return to the circuit.

"Rosberg must have had an issue on that last lap, he dropped 1.3 seconds to Hamilton so has he had a small moment somewhere?
Rosberg has been asked by his team to close up on leader Hamilton in case the safety car is brought out.

"Ferrari gave us some hope through free practice with Sebastian Vettel fastest of all in the last session. Rosberg doesn't want to have pressure from Vettel, it limits your strategy calls. It's reasonably bunched up right back to Verstappen."
Vettel, third, is narrowly down on Rosberg while Verstappen is in eight.
Sebastian Vettel is certainly keeping Ferrari in the hunt for a first Monaco GP win since 2001. Mercedes' advantage over Vettel will not be as healthy as they would like. He's 1.6s behind Nico Rosberg, who is told to start closing the gap on his team-mate Lewis Hamilton.
World Champion in 1992 Nigel Mansell tweets:, external "Lewis will build gap up to have in pocket for tyre stop, just flowing the corners driving slowly you drive faster, slow speed down. Really good to see Seb holding on to Mercs. Lewis for me just saving tyres and brakes which is a little surprise ,you should be able to push."
Carlos Sainz, who started from the pit lane, is up to 15th but pits to swap from supersofts to soft tyres. Valtteri Bottas and Marcus Ericsson also make their first stop of the race from 13th and 14th respectively.

"It wouldn't be the first time that Lewis Hamilton has said something while having a lead that sets hearts racing. He's got margin right now."
Possibly some concern for Lewis Hamilton as he asks over team radio in a concerned tone: "What can I do to save those brakes, I'm having to drive so slow right now."
The gap between himself and Nico Rosberg, in second, is now 2.4s.
Daily Mirror journalist Byron Young: "Nico Rosberg's tyres one lap older than Lewis Hamilton's...will he use that to shout for an earlier stop? Hamilton has priority."
Reece Young: Race has settled down as a gap of at least two seconds stands between each driver. Typically Monaco-esque race so far.
Alex Withington: Is this the race where McLaren finally get some points? Looking good so far.
Ashley Norris: Maldonado must be aiming for a record-breaking amount of DNFs. It's getting absurd.
